Minecraft Launcher is the official Mojang client for starting Minecraft on Windows, so there is no need for a third-party tool. This page covers version 2.0.0.0, a 2.1 MB file that costs nothing and needs Windows 10 or later. The installer is fetched from launcher.mojang.com.
Who needs Mojang's launcher on Windows 10
The launcher suits anyone who plays Minecraft on a Windows 10 or later PC. Mojang publishes it as the official entry point for Minecraft, a sandbox voxel game.
It is tagged with Minecraft Java, Minecraft Dungeons and Minecraft Legends.
What the launcher does in practice
Its job is to start the game. Exploring your own world, surviving the night and building freely describe the game itself, not launcher tools.
Cost, licence and size limits
The launcher is free and uses a proprietary licence, so the source code is not open. At 2.1 MB it is a small download. It was last updated on October 4, 2025.
